rogaining 

A particularly munt-filled beer drinking event. Competitors compete head to head in an event in which they must skol one beer at each of five stations, and sprint around 50m between stations (often a circuit is set up with the first and last stops at the same station). Notorious for shaking and bloating the stomach while drinking, causing mass amounts of high-velocity chunder into bins which are generally kept at the stations.

D'ya see him munt all over himself at the rogaining?

Remainings 

A cool roblox Youtuber that originally started small when he was in middle school and made a lot of Mr. Clean and OxiClean jokes when he was smaller and started making more serious content. By the time this definition is being made, he is almost to 300k subscribers and doing well in the Roblox Star Program.

Dude I just watched Remainings play Plates of Fate and that Starworks dude died a lot.

Don't piss on my leg and tell me it's raining. 

Don't hurt me and then pretend like you had nothing to do with it.

You argued, privately, to each member of the committee that I should be fired and now you come by on my last day to tell me how sorry you are about what "happened." Don't piss on my leg and tell me it's raining.
